Be it known that I,- R0r S. ,INNES, a'citizen of the United -States,'-resid1ng atMadie son, in thecounty of Lake and State. of South Dakota, have inventedecertam new and useful Improvements: in Automobile Radiator-Thawing Devices, ..of:. which the following is a specification.

This invention relates to certain new and useful improvements in radiator thawmg devicesand the primary object thereof is to provide means for automatically effecting thawing of the ribbon tubes upon freezlng thereof. 1 I

The invention-briefly proposes the use of an overflow pipewhich is modified so as to receive the steam that is generated in the radiator upon running of the engine and ,to distribute same at various points throughout the radiator to thereby efli'ect heat ng hf the frozen water and consequent thawing thereof.

The'invention has for its further ,object simple. and inexpensive modification of the overflow pipe and still further aims to rovide means of the'cha-racter set forth w lch can be easily and quickly attached to the radiators of automobiles now in use or which can be built into the radiators during manufacture of the latter.

4 In the drawings I Figure 1, is a rear erspectlve new of an automobile radiator, s owing the present invention applied thereto as an attachment;

.Figure 2, is a detail view partlyin section f shfiwing the present inventlon built into a iator at the time ofmanufacture thereof; Figure 3, is a transverse sectional view of a radiator having the invention built therein; y 7 r I Figure 4, is a detail perspective view of in section;

Figure an a detail view of the attaching strip, and o Figurefi, is a transversesectional vlew showing the manner of securing the attaching strip to the parts. In proceeding in accordance w1th the present invention, the "overflow pipe I, has its upper end 2 completely closed, while its lower end is open to permit the escape of the the overflow pipe, partly broken away and' overflow or surplus. water. A relatively largesteam and water inlet 4:v is provlded at I the radiator R.

mately" U-shape in cross-section receiving the ' pipe.

" of the pipe is formed throughout with a an attaching strip 5 being employed to rigidly connect the pipe 1 to the rear side of The strip 5 is of approxi- 'let- 4 in the filling neck N of the radiator,

and soldered at 7 to the pipe ,1, and has wings 6 which are also soldered to the radiator, in the instance of the invention being applied to. radiators" now in use, or otherwise stated radiators that are not especially built for use with the present invention.

In cases where the'invention is to be built into the radiator, or incorporated therein,

during'manufacture, the rear sides of the cells or as generally termed the honey-comb,

are cutaway to afford a vertical channel or chamber 8 of suitable size to receive the pipe 1, The pipe 1 is preferably soldered in place at 8 and is covered by a flat metal strip or plate 9 which latter'is soldered to Y the rear side of the honey-comb and to the pipe to assist in securing the latter in. place. In operation, as the steam rises in the by the circulation thus set up to the adjacent cells, until the entire radiator becomes thawed out. Byhaving the upper end of war 1y therefrom, after having entered the The inlet t also serves to receive any overflow of water in filling of the radiator. What is claimed is:- 1. In combination. with an automobile radiator, an overflow pipe disposed vertically and centrally. of the width'ofthe radiator and having a closed upper end andaninlet 'frozen radiator, same enters the inlet 4 and escapes throughthe outlets 3 and is caused to impinge against the radiator cells, meltipe closed, the steamcannot escape up- I arranged in the'filling'neck of the radiator,

said pipe extendingsto a point ddjacent the lower end of the radiator and formedwith a series of outlets, the said outlets being so disposed as to cause steamentering the pipe q at the inlet thereof to egress through the outlets and be impinged against the a jacent cells of the radiator on opposite sides-of ther a series of outlets, the said outlets being so disposed as to cause steam entering the pipe at the inlet thereof to egress through the outlets and be im inged against the adjacent I cells of the radiator on opposite sides of the pipe to effect thawing of the latter and means to attach the pipe in position including a metal member extending transversely across the channel and pipe engaged over the outer side of the overflow pipe and connected to the radiator.

3. In an automobile radiator thawing de- 1 vioe, a .pipe having an inlet at its top and.

iormedto extend within the filling neck of the radiator, said pipe formed with a series of steam outlets arranged to cause the steam from the ipe to be directly impinged against I the radia or, and 'tobe diffused on op osite sides of the-pipe, and-means to affix sai pipe to the rear si e portion of the radiator and at substantially "the center of the Width of the radiator.

4:. In combination with an automobile radiator having a central vertical channel formed in'the rear side of its cells, an overflow pipe engaged in said channel and having an lnlet arranged to extend in the filling neck of the radiator, said pipe extending to a point adjaoent'the lower end of the radiator and being formed with a-series of outlets, the said outlets being so disposed as-to cause steam entering the ipe at the inlet thereof to egress. through t 1e outlets and be im inged against the adjacent cells of the re iator to eflect thawing of the latter, and

means to connect the pipe to the radiator.

Intestimony whereof I allix my signature.
